Title: Osteoinduction of cortical bone allografts by coating with biopolymers seeded with recipient periosteal bone cells
Inventor: LEWANDROWSKI KAI-UWE
IPC: A61F2/06
Filed: 1999-08-12
Abstract: A method by which immune responses to cortical bone grafts and other substrates (e.g., cement, 1PN, etc.) can be minimized and at the same time graft osteoinductive potential can be improved, and improved graft substrate materials are disclosed. The method of the invention provides new types of bone grafts that incorporate into host bone more thoroughly and more rapidly, eliminating long-term complications, such as fracture, non-union, infection, and rejection. In the method of the invention, bone grafts or other substrates are modified to have an osteoinductive surface modification that the recipient's body will accept as its own tissue type and therefore will not reject or otherwise cause to fail. The osteoinductive surface modification comprises a biopolymer matrix coating that is seeded with periosteal cells that have been previously harvested either from the graft recipient or from an allogenic or xenogenic donor source.

Title: Process for producing optically active tropinonemonocarboxylic acid ester derivative
Inventor: NODE MANABU
IPC: C12P17/10
Filed: 1999-07-12
Abstract: An optically active tropinone monocarboxylic acid ester derivative, which is useful as an intermediate in synthesizing an optically active tropane derivative, is reacted with succinedialdehyde, an organic amine and acetone dicarboxylic acid ester to thereby give a tropinone dicarboxylic acid ester derivative. Then, the obtained product is subjected to enzymatic asymmetric dealkoxycarbonylation followed by reduction and dehydration to thereby give anhydroecgonine methyl ester. The thus obtained anhydroecgonine methyl ester shows the same optical rotation as anhydroecgonine methyl ester obtained from natural cocaine, which indicates that the former product has the same absolute configuration as the latter. In the asymmetric dealkoxycarbonylation, the optically active tropinone monocarboxylic acid ester derivative is obtained at a yield of 30 to 50 mol% and shows an optical purity of 70 to 97 %ee. By further reducing and dehydrating the optically active tropinone monocarboxylic acid ester derivative, a crystalline optically active anhydroecgonine carboxylic acid derivative can be obtained.  Thus, it is found out that the optical purity can be easily elevated by recrystallization.

Patent CA-2351523-A1 (CA)
Inventor: RAJEWSKI ROGER A
IPC: B01D61/14
Filed: 1999-09-09
Abstract: A process and apparatuses (10) are provided for continuously harvesting particles from organic solution-laden near critical and supercritical fluids. Broadly, the processes and apparatuses utilize a filter or separator (56) comprising a thin membrane (70) supported on a sintered stainless steel tube (72). A feed stream comprising the desired particles, a supercritical antisolvent for the particles (preferably CO2), and a solvent for the particles, is contacted with the membrane layer of the filter under supercritical conditions for the mixture of antisolvent and solvent. The preferred antisolvents are substantially miscible with the solvent and have a critical temperature of less than 160 °C. The desired particles are retained by the filter while the solvent and most of the antisolvent pass through the filter, resulting in separation of the particles from the solvent.

Title: Buffer management for support of quality-of-service guarantees and data flow control in data switching
Inventor: CHANG RONG-FENG
IPC: H04L12/54
Filed: 2001-08-17
Abstract: A method of utilizing shared memory resources in switching Protocol Data Units (PDUs) at a data switching node is presented. The method includes reserving: a temporary memory storage portion for storing PDUs prior to queuing for processing thereof, a Class-of-Service memory storage portion to provide support Quality-of-Service guarantees, a shared memory-pool portion and an input port memory storage portion enabling non-blocking input port flow control. Provisions are made for PDU discard decisions to be delayed until after PDU headers are inspected subsequent to the receipt of each PDU.      Provisions are made for well-behaved data flows conveyed via an input port to be protected against blocking from misbehaving data flows conveyed via other input ports of the data switching node. The advantages are derived from a memory management scheme which can be equally applied in a PDU discard and a flow control environment to reduce PDU discard instances at a data network node implementing the memory management scheme while reducing memory storage requirements.
